Overview

Container technologies have traditionally not provided a way for storage to remain once the container itself has ceased to exist. Given the temporary nature of containers, this limitation often resulted in data loss or necessitated the use of complicated, external storage solutions. However, in Kubernetes, a volume is designed to last at least as long as the Pod it’s attached to, rather than the individual containers. This means that even if a container…
